Explanation:

A geographic advantage Asoka forces had against the kalingans that the land Asoka had already surrounded Kalinga.

The Kalinga area is connected with the Mahendragiri mountain, which is located in Odisha's Ganjam district, near its border with Andhra Pradesh. Kalinga's southern boundary used to reach all the way up to the Krishna River.

More than 100,000 people were slain at the battle of Kalinga, and 150,000 were taken prisoner. Many mothers and children suffered as a result of this. This conflict had an influence on Ashoka, and he determined not to fight any future wars. He made the decision to spend the remainder of his life to spreading the dharma.

Therefore, it can conclude that Asoka's armies enjoyed a geographical edge over the Kalingans since Asoka had previously encircled Kalinga with territory.

Physical maps show natural features such as vegetation, rivers, mountains, and deserts. They do not typically display human-made features like settlements.

Explanation:

Physical maps are designed to show the natural features of the Earth. They typically display elements such as:

Vegetation - Areas of natural plant life, such as forests and grasslands.

Rivers - Bodies of flowing water that travel across the land surface.

Mountains - Elevated areas of land, usually with steep slopes and significant height differences.

Deserts - Arid regions with very little precipitation, often characterized by sand or rock.

Unlike other types of maps, physical maps do not usually focus on human-made features like settlements.

the answer is D hardness

Denver's lower station pressure compared to Chicago is due to its higher altitude, which results in less atmospheric pressure from the reduced air column above it. This affects vapor pressure and humidity, which are important factors in climate modeling and local weather patterns.

The reason Denver always has a lower station pressure than Chicago can be attributed to altitude and the physical principles of barometric pressure. Denver, known as the Mile-High City, is located at a higher elevation than Chicago. According to the hydrostatic equation, at higher altitudes, the barometric pressure is much less because the pressure is produced by the weight of the column of air above the location pressing down. Therefore, Denver experiences a lower atmospheric pressure compared to Chicago, which is closer to sea level.

Climate modeling further suggests that lower vapor pressure associated with altitude contributes to the higher humidity in the north-central United States. This decrease in vapor pressure is significant, amounting to a 2% decrease, and it influences weather patterns and humidity levels, especially near large bodies of water like the Great Lakes.

The ocean regulates temperatures, keeping them mild year-round in moderate climate regions.

The correct answer is B. moderate climate regions.

The ocean has a moderating effect on the climate in coastal regions, keeping temperatures mild year-round. Ocean currents distribute heat and regulate temperatures, creating a more stable climate compared to inland areas.

For example, cities like San Francisco in California and Lisbon in Portugal experience mild temperatures throughout the year due to their proximity to the ocean. In contrast, cities located further inland, such as Phoenix in Arizona, have more extreme temperature variations.

It is appropriately correct to mention that a gemstone is a hard colorful mineral with a glassy or shiny luster. Therefore, the statement given above is true.

A mineral can be referred to or considered as a substance or an element that is found in the sources of nature, and do not have any artificial composition within their structure. They may be solid, gaseous, or liquid in their composition form.

A mineral like a gemstone is known for its crystalline composition. Due to this composition, it becomes shiny, and also gives reflection, which is similar to the one done by a glass. Gemstones are naturally occurring, however, they can also be created artificially.

Therefore, the statement given above regarding gemstone as a mineral holds true and has been aforementioned.

There are a few pros and cons of the NAFTA agreement.

Pros: It increased trade between US, Canada, and Mexico. Trade between the three countries increased to $1.14 trillion in 2015. This increased our economic output boosting US growth by about.5% a year. This then created lots of jobs about 5 million new American jobs. Also now there was now more foreign investment in the US businesses which increased profit. And finally this agreement lowered prices because of the loss of tariffs. We relied less on the middle east for oil and more on Mexico this also reduced gas prices as transportation was cheaper. Cons: NAFTA Also made the US lose a lot of jobs we lost fewer jobs than we gained apparently but still it was about 500,000 to 750,00 jobs which are substantial. This was because manufacturers moved to Mexico as labor is much cheaper there, this job migration negatively affected wages as well. Companies would lower wages and threaten their workers to move to Mexico if they unionised this worked and a huge chunk of American. Manufacturing companies do this. NAFTA also put about 1.3 million Mexican farmers out of work causing them to be forced to illegally migrate to the US as they were desperate for work. Illegal immigrant numbers spiked after NAFTA. The Mexican workers who stayed behind in Mexico worked for these US companies and are treated badly they work in substandard conditions for terrible wages and 30% of Mexicos labor force works in these jobs. They also degrade Mexicos environment to lower costs causing 36 billion a year in pollution and cutting down 630,000 hectares of forest a year also contributing to global warming.

So overall it increases trade, profit and growth of these companies as well as cheapening products but people lose jobs lose their rights in the workplace and is degrading the Mexican environment.

The correct answer is - It appears as if the average global surface temperature increased by 0.6 degrees.

The trend of global warming has been becoming more intense, and thus more obvious in the past few decades. In big portion it is a result of the human activity because it contributes to increased amounts of carbon dioxide in the atmosphere which is the main gas that forms the Greenhouse effect, as well the destruction of the ozone layer which contributes to increased influence by the sun on the Earth's surface. The temperature of the surface has risen 0.6 degrees (at places 0.9), while the average air temperature has gone over 1 degree all over the world.
